The Romantics actress, who turns 35 this month, debuted a new, sophisticated, chocolate-brown hair color and shorter, cleaner cut at the Z100 Jingle Ball in NYC last weekend. The transformation was so subtle that fans nearly missed her new beauty look, which includes a color nearly identical to Kate Middleton's November transformation.

When it comes to her locks, the fresh-faced star is also an executive! Back in January, Tom Cruise's ex-wife signed on to become a co-owner and celebrity spokesperson for Alterna Haircare, a natural, organic beauty brand. "It's good for my hair and good for the earth, so I feel good using it," the brunette star said in a statement when the partnership was first announced.
